FOLDING STAND.

To all whom it may concern.'

Be it known that l, PETER PLANTINGA, a citizen of the United States, residing at liorcester, in the county of TWorcester and State of lifassachusetts, have invented a new and useful Folding Stand, of which the following is a specification.

This invention relates to a folding stand which while capable of use for several purposes, is especially adapted, in one of its forms, for supporting the bells or chimes which the trap drummer of an orchestra opcrates.

The principal objects of the invention are to provide a construction in which the parts can all be folded up into a small space and so made that the 'weight of the entire device will be very small and which can be made in a simple and inexpensive manner, preferably of sheet metal.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings which show certain forms in which the invention may be embodied and in which,

Figure 1 is a side elevation of one form of the invention suitable for supporting the bells. Fig. 2 is a plan ofthe same. Fig. 3 is a side elevation showing the base of the device folded up. Fig. 4 is a similar view showing the upper part folded up. Fig. 5 is a fragmentary side elevation on enlarged scale showing certain details of construction. Fig. 6 is a plan showin@ another form in which the invention. may be made, and Fig. 7 is a plan of the top frame shown in F ig. 6 illustrated in folded position.

The device is base consisting o a collar or support 16 having ears 11 thereon, each provided with a pivot 12 on which swings a leg 13. rihese legs are provided witl projections le extending u wardly above the pivots and with an angulidr face on the edge which when the legs are spread out, comes into contact with the side of the collar so as to hold the legs in proper position to support the device.

ln order to adjust the height of the device the collar is made hollow and a vertical rod 15 is located in it. This rod may be adjusted vertically and held in adjusted positions by means of a thumb screw 16. rifhe rod extends upwardly into a second collar 20 which may be fixed to it or adjusted along it in the same manner as that described above, or in Speecation oi Letters atent.

tops. Others of these arms are provided.

with supports 27 of similar form but lacking the pivot and having a rivet 28 instead, or some other fastening means, so that the member 27 will be fixed on the end of the arm.

The supports 26 and 27 support a frame 31 preferably by means of a pin and socket connection. For this purV ose the former are shown as provided witi upwardly proecting pins 30 on which a horizontal frame 31 is pivoted. This frame is preferably fixed so as to swing about the pin 30, as indicated in Fig. 2. A supporting means is thus rovided which in the form shown in that .gure consists simply of two of these frames each having a joint 33 at the center so that they can be folded up. It will be seen that in this form of the invention, the horizontal frame 31 may be folded up on itself and swung down on the arm 22 to which it is permanently pivoted so as to assume the position shown in Fig. 4 in which the parts will take up very little room. Villen the horizontal frame is formed in two separate pieces in this way, the parts can all be folded up into small compass. This forni of the invention is shown as involving two of these parts 31, one longer than the other so as to carry the bells. The invention, of course, may be carried out with the two members of the frame of the same length and in fact the two members may be connected as is shown in Figs. 6 and 7. In this case the arms 22 are made in the same way as before but preferably all of them are provided with stationary ends 27 and the frame is removable therefrom. ln this case the supporting means consists of four members arranged in pairs being pivoted at 33 as above and the ends of the two pairs 35 being connected by straight integral bars 36 to provide a square or other shaped form. This frame is provided with pivots 37 at the corners and with perforations 38 for receiving the pins 30.

In all forms shown in the drawings, the arms 22 or legs 13 are provided with angular projections which engage the vertical surfaces of the collars l0 and 2O so as to hold them at the proper angle and those arms which are provided with pivoted supporting members 26 are also provided with similar projections 24, as has been stated to support the frame in a horizontal position in the same way.

In all cases the parts of the device can be constructed at very small expense and of light material which can be folded up into small space so as to be easily portable.

The constructions shown and described may be greatly varied by a skilled mechanic without departing from the scope of the invention as expressed in the claims.

I-Iaving thusfully described my invention, what I claim and desire to secure by Letters- Patent of the United States is 1. A folding stand comprising a plurality of arms, and a foldable horizontal frame mounted on the upper ends of said arms, said frame having a permanent pivotal connection with one of said arms, and that arm having another pivotal connection at an angle to the first pivotal connection on which the first named pivotal connection and frame are swingingly mounted.

2. In a device of the character described, the combination of a horizontal frame having joints therein, whereby said frame is adapted to be folded up, and means for supporting said frame comprising arms having flat upper surfaces on which the frame is adapted to rest, one of said arms having a detachable connection with the frame and another a permanent connection therewith comprising two pivots located in different planes, whereby it may swing on two axes.

3. In a device of the character described, the combination of a horizontal foldable frame, a set of arms for supporting said frame, and connections between certain of said arms and said frame comprising a member horizontally pivoted on the arm, having thereon a pivot at right-angles to the horizontal pivot about which said frame is adapted to swing.

4. A folding stand comprising a set of arms, a frame adapted to be supported thereby, and connections between said arms and the frame comprising a member horizontally pivoted on certain of the arms having thereon a pivot at right angles to said horizontal pivot about which said frame is adapted to swing.

5. In a folding stand, the combination of a vertical standard, arms pivotally mounted thereon and adapted to extend vertically therefrom and to swing out so as to extend upwardly at an angle, one of said arms being provided with a vertical pin on its upper end, and the other of said arms having an end piece pivoted thereon to swing about a horizontal axis and providedwith an unwardly extending pivot, and v`a' Vhorizonta frame mounted to swing about the last mentioned pivot and adapted to removably engage said m. p 6. In a folding stand, the combination of upwardly extending foldable arms, certain of said arms being each provided with an up- Y`wardlyl extending pin, and one of the arms having an end vpiece horizontally pivoted thereon and provided with an upwardly extending pin, and a horizontal support permanently secured to the last mentioned upwardly extending pin, and having perforations whereby it is adapted to be removably connected with the first named pins.

7. In a folding stand, the combination of upwardly extending foldable arms, certain of said arms being each provided with an upwardly extending pin, and one of the arms having an end piece horizontally pivoted thereon and provided with an upwardly extending pin, and a horizontal support permanently secured to the last mentioned upwardly extending pin, having perforations whereby it is ada ted to be removably connected with the first named pins, and consisting of a lurality of parts pivotally connected toget er by vertical pivots, whereby said supporting means is adapted to be removed from certain of the arms and folded up against the arm on which it is mounted.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.

PETER PLANTINGA.
